strengths:
this barrel has awesome looks! (mines black) but that's not the important part. mine is 16 inches long and is a reasonably quit barrel with a loud marker like a tes.price is also a + its only 30-40$.and comes in plastic barrel case>:)

flaws:
there are two minor flaws.Its accuracy slides off as the barrel gets older in fact the first month i could get a 1-2in grouping but after a month or two that grouping changed to 5-6inch groupings and etc.I mean like the accuracy is now worse than the stock barrel:(
and it is actually Farly heavy its like its got some mini magnets attracted to the ground making it heavy.

Conclusion:

Overall the barrel is ok for the price but the two flaws are pretty much the only things that matter in a barrel.
I love check it products!!! But this barrel gets a 7 for not staying in its prime:(
Hope this helps.
